Ghostly Harrison

He grew up on Rockhopper Island, centuries before the alternate dimension Rockhopper discovered it. Harrison found that the Fountain of Youth was located on the island, and drank from it, giving him immortality.

Centuries after this, Rockhopper came to the island, and sent all the Polar Bears into the ocean. Most of the Polar Bears were able to swim to Club Penguin, where the Great Polar Bear War of Club Penguin began. Most of the Polar Bears died, except for Hungry Herberta, and Happy Herbert.

As a ghost, Harrison later moved to our dimension, where the Poltergeist Extermination Program captured him. His current location is unknown.

Trivia

Unlike Herbert P. Bear, his descendant, he liked penguins and enjoyed being around them.
